deviriation settlement. The dam seismicity investigation resulted in acceptable state where it had no ground tilting, dam cracking, liquefaction processing, and seiches action. In conlucion, the overall assessment of major inspection of Keuliling Reservoir presented that the dam can serve and operate optimally. 4. DAM OPERATION UNIT The operation and maintenance of a dam must be organized in accordance with standards, operations and its guidelines. The observation works of Keuliling Dam aims in analysing provision data that will result in the state and behavior of the dam whether something is running normally or not. Here, the Dam Operation Unit performing the dam monitoring as one of the main tasks of River Basin Organization of Sumatera – I. The most recent Keuliling Dam monitoring conducted in November 2017 where it is the third investigation in one year. The unit was monitoring and observing the behavior of dams visually, also reading the instrumentations equipment as a basis and analysis material to evaluate the performance of the dam in order to be followed up if there is a critical situation. The organizational structure of observation and maintenance of Keuliling Dam is organized under the Dam Operation Unit (DOU) – River Basin Organization of Sumatera I. The organizational structure with number of personnel and the quality of personnel required is a matter of concern in preparing an effective and efficient operation and maintenances organization. The need for personnel required in a dam organization structure is determined by the level and type of complex of a dam construction. Organizational structure of observation and maintenance of Dam Operation Unit in Keuliling Dam is presented in Figure 2.
